SNARLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 459,602, dated September 15, 1891.

Application filed August 1, 1890. Serial No. 360,717. (No model.)

I 0 all whom, it may concern: 1

Be it known that I, THoMAs A. TR1PP,of New Bedford, in the county of Bristol and State of Massachusetts, have invented an Improved Snarling-Machine, of which the fol lowing is a specification, reference being had to the accompanying drawings, in Which Figure 1 is a perspective illustrating a portion of a machine embodying my invention. Fig. 2 is a modification.

In the manufacture of a variety of hollow articles figures, usually ornamental, are formed by a method called snarling, and the machines for doing this Work are called snarling-machines.

The object of my invention is to produce a cheap and simple snarling-machine in which the snarling-tool is vibrated with substantially uniform rapidity and has a uniform amplitude of vibration; and my invention consists in the combination, with a snarlingtool,whicl1 is supported at one end, of a cam, which engages the snarling-tool between its ends.

In the drawings, the snarling-tool A is mounted on a support A, and a cam B, carried by shaft 1), engages it at a proper distance from support A to cause its free end to vibrate rapidly. As the cam rotates it rubs against the snarling-tool. thus vibrating it regularly, and gives it a uniform amplitude of vibration, as will be plain from the draw- I ings. The outer end of the snarler A being set in vibration and the article held by the workman in properrelation to the free end of the snarler, the vibrations of the snarler cause the metal to bulge out at the desired point. The workman moves the article as he desires over the snarling-tool, the free or Work end of which is of any desired shape.

In the modification illustrated in Fig. 2 cam B en gages the under side of the snarlingtool instead of the upper side, as in Fig. 1.

dated February 15, 1876, and disclaim all that is shown in it. Soligny hammers his vibrating snarling-iron between its ends, his hammer moving out of con tact with the iron after the blow is struck, just as if the hammer were a hand-hammer. In my machine the cam is at all times in contact with the iron, and gives the iron a radically-different motion from that given by blows of a hammer.

IVhat I claim as my invention is In a snarling-machine, the combination of a snarling-iron, fixed at one end, with a cam in constant rubbing contact with the iron between its ends, substantially as and for the purpose set forth.
